Objective: To compare the surgical subspecialties performing bladder exstrophy closures and characterize their practice patterns using both a national and institutional database. Methods: The National Surgical Quality Improvement Program Pediatric (NSQIPP) database was reviewed for all bladder exstrophy closures performed from 2012 to 2017. A single institutional exstrophy-epispadias complex database of 1337 patients was reviewed for patients with a bladder closure at a referring institution from 1975 to 2018. Patients with cloacal exstrophy were excluded. The subspecialties of the surgeons performing the closures were identified. Practice patterns such as the use of a pelvic osteotomy and postoperative immobilization, and perioperative outcomes were compared for each subspecialty group. Results: A total of 84 bladder exstrophy patients from NSQIPP and 263 from the author's institutional database met the inclusion criteria. From NSQIPP, 88% of closures were performed by pediatric urologists while 12% were done by other subspecialists. From the institutional database, 75% of referred bladder exstrophy closures were done by a pediatric urologist, and 25% by other services. Gender, race, operation time, length of stay, and postoperative complications were not significantly different between the groups. In one database, pediatric surgeons performed closures earlier, and in another database, pediatric urologists had greater utilization of osteotomy with different immobilization techniques. Pediatric urologists had a higher success rate. Conclusion: Pediatric urologists performed the most bladder exstrophy closures in both databases; they operated on more delayed closures with a greater use of adjunctive procedures and a higher success rate. Differences in surgical training may contribute to the differences in practice patterns.
